edl: add a way to add tags
Add new header which shows up as tags/metadata (associated with
--display-tags). The way this is added means it doesn't always work,
because root->meta (see code) can be NULL for some absurd reason. But it
works for the one case I intended to use it (ytdl_hook, see next
commit), though only in default configurations.

This metadata is supposed to be informational, much like for example ID3 +tags in audio files. Due to lack of separation of different kinds of metadata it +is unspecified what names are allowed, how they are interpreted, and whether +some of them affect playback functionally.

Another consequence of this is that FFmpeg "normalized" +tags are recognized, or stuff like replaygain tags.) + +Example:: + + !global_tags,title=bla,something_arbitrary=even_more_arbitrary + +Any parameter names are allowed.
